Abstract: 6101 aluminum alloy extrusions with different front beam outlet temperatures were aged by different aging processes, and the 6101 aluminum alloy specimens after corresponding heat treatment were tested by OM, SEM, EDS, tensile test, conductivity test and other test methods. The results show that the comprehensive properties of the 6101 alloy are preferable when the front beam outlet temperature is 450 ℃ and the process is aging at 280 ℃ for 48 h, the tensile strength is 132 MPa and the conductivity is 59.8%IACS. When the front beam outlet temperature is 500 ℃ and the process is aging at 270 ℃ for 48 h, the 6101 alloy can obtain preferable comprehensive properties, its tensile strength is 141 MPa and conductivity is 59.7%IACS. Under the both process conditions, 6101 aluminum alloy extrusion can meet the product requirements of high strength and high conductivity characteristics.
